Biosphere powerpoint

  1. 1. The Biosphere Jessica Henderson
  2. 2. NCSCOS Goals and ObjectivesObjective 5.01 Investigate and analyze theinterrelationships among organisms,populations, communities and ecosystems Techniques of field ecology
  3. 3. Biosphere• Ecosystems were originally distributed over the globe and how climates determined the characteristics of the major biomes, such as forests, deserts and grasslands.• Each of the biomes are mixed with its own species which adapt to the environmental conditions.• Get the image of the day, See what the biosphere looks like today. http://earthobservatory.nasa.gov/IOTD/view.php?id=2669
  4. 4. Biosphere and The Climate• Climate -> the prevailing weather conditions in a particular region.Climate is dictated by temperature and rainfall.The distribution of solar energy caused by spherical Earth, and the rotation and path of the Earth around the sun, affects how the winds blow and the amount of rainfall received in various regions.
  5. 5. Patterns of biome distribution • Patterns of the world biomes in relation to temperature and moisture. • The same type of biome can occur in different regions of the world .
  6. 6. Terrestrial Ecosystems• Biomes of the World (video). http://www.youtube.com/watch?v=WZGCZY47YS0&feature=related• A major type ofterrestrial ecosystemis called a biome.A biome has a mixtureof plants and animalsthat adapt to livingconditions andenvironmentalconditions.
  7. 7. Tundra• Arctic tundra biome – Encircles the Earth just south of ice-covered polar seas in the Northern Hemisphere. – It covers about 20% of the Earth’s land surface. – It is cold and dark much of the year. – It has extremely long, cold, harsh winters and sort summers.
  8. 8. Taiga• The Taiga or boreal forest exists the south of thetundra and covers 11% of the Earth’s landmasses.The taiga consist of two forests: 1. Coniferous Forest 2. Temperate Deciduous Continue on….
  9. 9. Coniferous Forest• The Coniferous Forest is sometimes called the temperate rain forest. • Coniferous forests has the tallest conifer trees and coastal redwoods. • Has plenty of rainfall and rich soil. • It also has ferns and mosses.
  10. 10. Temperate Deciduous Forests• Temperate Deciduous forests has trees such as oak, beech, sycamore, and maple. • The tallest trees form a canopy over the upper layer of leaves to receive the sunlight first. • Enough sunlight penetrates the to provide energy for another layer of trees called understory trees.
  11. 11. Tropical Forests• Tropical Forests is located in South America, Africa, and the Indo-Malayan region near the equator.• The weather is always warm, rainfall is plentiful, and is the richest of the biomes.• The primary levels of the rainforest are the canopy, the understory and the forest floor.
  12. 12. Desert• The Desert is in the Northern and Southern Hemisphere.• The day is hot because of the lack of cloud cover and the sun penetrates easier and nights are cold because the heat escapes in the atmosphere.• The plants and animals store water for protection and for photosynthesis.
